[RESOLVED] memory choices

[revRazor]

I'm doing my first build, its for 3d CAD and rendering (student level). So far I got a i7 920, quadro fx 580, and asRock extreme mobo. I'm trying to decide on memory, I want 3 sticks with 2 GB each, so far broke it down to these four:

OCZ3G1600LV6GK, 1600MHz, PS3 12800, 8-8-8-24, $110 good balance, good price

OCZ3X1600LV6GK, 1600MHz, PS3 12800, 8-8-8-24 or it can run with
1800MHz, PS3 12800, 9-9-9-28 $160 good reviews

OCZ3P1600LV6GK, 1600MHz, PS3 12800, 7-7-7-24 $145 I read that lower latency is more important than higher speed for 3d aps.

CORSAIR XMS3 TR3X6G1600C8 G, 1600MHz, PS3 12800, 8-8-8-24, $155 This one has very high ratings at newegg.

All of them are DDR3 240 pin and run on 1.65V.

Any other suggestions would be helpful but I would really like to narrow it down. Thanks for your help.
